Application filed December 10, 1920. Serial No. 429,682.

To all whom it may concern:

Be it known that I, THOMAS H. SANronD, a citizen of the United States, residing at Alexander City, in the county of T allapoosa and State of Alabama, have invented certain new and useful Improvements in a Brake-Shoe, of which the following is a specification.

This invention relates to a brake shoe and has for its principal objects the production of means to connect a brake shoe and its head, so that they be securely held together when so desired.

Another object of the invention is to generally improve upon brake shoes of this character by providing a device which will be of extremely simple, durable and lIlGXPGlL sive construction, one which is efiicient and reliable in operation, and well adapted to the purpose for which it is designed.

With these and numerous other objects in view, the invention resides in certain novel features of construction, and the combination and arrangement of parts as will be hereinafter fully described and claimed.

In the drawing:

Figure l is a side elevation of the brake shoe and a portion of the brake head,

Fig. 2 is a vertical central section taken through the brake shoe,

Fig. 3 is a plan view of the brake shoe, and

Fig. 4 is a section taken on the line 4- of Fig. 3.

Referring to the drawing by numerals it will be seen that 1 designates the brake shoe which may be of any preferred construction having the lugs 2, 3 and a projecting from the convex face thereof and it will be noted by referring to Fig. 1 of the drawing that'the lug 3 has slating side portions so as to be dove-tailed. The brake shoe 1 is provided with any preferred construction upon its wearing surface which is adapted to engage the car wheel in a well known manner.

The brake head 5 is attached to the usual operating mechanism and comprises a curved body portion and upon the concaveface thereof is provided with the grooves 6, 7 and 8. A slot 9 communicates with the groove 6 from the under side thereof and a similar slot 10 communicates with the groove 8. A dovetailed slot 11 communicates with the groove 7 as is shown more clearly in Fig. 4 of the drawing. A latch pocket 18 communicates with the groove 6 from the upper slde thereof and has pivotally mounted therein the latch 14.

hen it is desired to assemble the brake shoe 1n connection with the brake head it will be readily seen that the latch 14 will be rotated so as to be wholly within the pocket 13. The lugs 2, 3 and i will then be placed centrally in the grooves 6, 7 and 8 and the shoe 1 will then be pulled downwardly so that these lugs 2, 3 and i will fit in their respective slots 9, 11 and 10. The slot 11 and the lug 3 being dove-tailed as described it will be seen that it will be impossible to pull the shoe from engagement with the head as long as the lug 3 is seated within the slot 11. In order to hold the various elements in the position just described the latch 14 will be forced into the position shown in Fig. 3 of the drawing whereby the latch engages the lug 2 thus preventing the shoe and head from sliding in relation to each other so as to become disengaged. Thus it will be seen that the device may be easily assembled and to disassemble same all that will be necessary is to knock the latch 14L from engagement with the lug 2 and the device may then be easily dis-assent bled in a manner which will be quite apparent. The keyway shown at 15 is used when it is desired to use my shoe in connection with brake heads now commonly in use.

It is thought that the construction and operation of this invention will be readily understood from the foregoing description taken, in connection with the drawing without a more extended explanation. As numerous changes in form, proportion, and in the minor details of construction, may be resorted to without departing from the spirit of this invention, I do not wish to be limited to the construction herein shown and described other than as claimed.

Having thus desoribedmy invention what I claim as new is A device of the class described comprising a brake shoe having a plurality of lugs projecting from the convex face thereof, one of said lugs being dove-tailed, a brake headhaving a plurality of transverse grooves extendlng across the concave face thereof and one of said grooves provlded with a dovetailed slot for receiving the dove-tai1ed lug In testimony whereof I afliX my signature on the brake shoe and the remaining grooves in presence of two Witnesses.

provided with slots for receiving the other lugs, a pocket formed adjacent one of said THOMAS SANFORD 5 grooves opposite its slot, and a latch pivot- Witnesses:

ally mounted Within said pocket for the O. C. THoMAs,
